55 total of the previous days'charges,\which inA this instance is thirty cents, so that the sub-f carriage 10 ance.

riagcs for the Fig. 4 position, and operatesl is connected to thetypewriter carriage 10 by f means of alug 11y mounted on the typewriter carriage and engaging a rack 12 on the computing carriage.

For convenreneethe machine is illustrated las adapted to maire ,out bills 13 for telephone with relation toi'he typewriter carriage 10,

that when the operator shifts the typewriter to position for writingin the iirst column 15 on the bill,l the totalizers 1, 2 are in position to b operated by the two right-hand master Wheels 5, 6. The Writing proceeds line by line in the usual manner, and after the irst three lines are written on the bill, each of thesetotalizers shows 30. The operator then shiftsthc carriages together until the temporary or sub-totalizer 1 is engaged by the master wheel 3, and also manipulates a hey 16 to set the machine for subtraction.' At this time the last column on the sheet -is at the printing point, and the operator writes on said column the amount seen on the sub-totalizer 1, namely, 30. it 'the same time this number is subtracted from the subtotalizer 1, the number being,

however, left in the permanent or grand totalizer 2. s

The operator then removes the bill from the machine and iiiiserts another bill and proceedsin the same manner, the total of the charges being printed in the right-hand column of said bill. and the sub-totalizer 1 inallj1 showing 0, while the grand totalizer 2 now shows the total of the two bills. ln like manner the operator proceeds to write all of the hills for the day.

On the secondhand each Isucceeding day of the month, each bill is again inserted by the operator into the machine, and new items are added as before I"Fig 2 shows the totalizers after the firstbill has been Written on the second day. amount to twenty-tive totalizer shows 25 The operator now shifts the typewriter and computing carriages over until the subtotalizer 1 registers with the carry-forward master vwheel 4, and at this timev adds on the sub-totalizer the totalizer now reads 55, as at Fig. 3. 'During this work, of range of any master wheel, and hence retains the amount 25. The amount30 is written on the work-sheet 13 in the special column 17 which may be headed Old bal- The operator then shifts the oar- The items on this bill f cents, and hence eac-h the grand totalizer 2 is-out4 the key 16 to set the machine for subtraction, and then writes in column 18 the amount which shows on the sub-totalizer 1, namely, this column 18 being headed New balance. Ofv course, after each operation of the clearing wheel 3 the operator restores 'the key 16 to set the machine back for addition.

It will be understood that when the parts are in the Fig. i position, and the sub-totalizer is engaged by the clearance master wheel 3, the grand totalizerl is clear of any master wheel and retains the amfuxnt therein. The grand totalizer, in fact, is not engaged by any master wheel except the grand master wheel G; whereas the sub-totalizer engages sucessively the sub-totalizing master wheel 5, the carry-forward master wheel el and the clearing master wheel One of the advantages of the improvements is that both sub-totalizing and grand totalizing can be performed, and the subtotalizer also cleared, all by the use of a.

single adding carriage and a single master wheel shaft. This simplifies the construction and operation of this class of machines, and the invention is also particularly valuable where it is desired to bring forward a prior bal` nce by adding the same in the subtotalizer without adding it in the grand totalizer. k

The master wheel shaft is power-rotated,

and is controlled by means et thel type-operated keys ot the typewriter, in the manner illustrated in the application of Gustave vDegener, No, 753,251, 'filed March 10, 1913 ion 21 orthe upper bevel pinion 22, thus reversibly driving the pinion 23 on the master wheel shaft 7.

Asset forth in said application, each of the totalizers comprises a series of computation wheels 24 having internal teeth to be engaged by the master wheel, and having also external teeth meshing with gears 25 on the'nulnber Wheels 26. y

The tens-carrying mechanism, as set 'forth in said applicatien, includes' a special tooth 27 on each computation wheel 24, and once in each revolution this tooth engages vand turns a tive-toothedwheel 28, which .forms one of a set of three rigidly connected wheels, the others being numbered 29'and 30. `The wheel 2,9 is turned far enough to enable one ot' its toothed points 31 to engage a 'constantly revolving pinion 32, which serves as a prime mover to complete the tenscarrying operation; said pinion 32 driving not only the which if i Q A iiei'ein sin 'ter ndi-@eis 'ti 'tens-cari 46, ant.
